This threat returns to a 1999 Trojan that infected the BIOS of a PC and is called even BEFORE the MBR is read!
The machines at risk are only those that use the Award BIOS and are running Windows.
This threat returns to a 1999 Trojan that infected the BIOS of a PC and is called even BEFORE the MBR is read!
There are more and more known viruses that infect the MBR (Master Boot Record). Symantec Security Response has published a blog to demonstrate this trend last month. However, we seldom confront with one that infects the BIOS. One of them is the notorious CIH appeared in 1999, which infected the computer BIOS and thus harmed a huge number of computers at that time. Recently, we met a new threat named Trojan.Mebromi that can add malicious components into Award BIOS which allows the threat to take control of the system even before MBR.
I purchased a new Sony VAIO desktop on Dec 29, 1997. By May 5th of 1998 I had reinstalled Win95 FIVE times and was sick of it. I went to Barnes & Nobel to look for OS/2 to see if Win95 would be stable in it, but while there I saw a paperback book, "Learn Linux in 24 Hours", by Bill Brush, for $25. It included a CD of RH5.0 in the back. My unstable Sony was stable as a rock running RH5.0, and I never bought OS/2 and never ran Windows again for personal use.
